Constructor Details

UncompressedStringDataChunk

public UncompressedStringDataChunk(int offset,
 String[] values)

Method Details

getValues

public String[] getValues()

getLength

public int getLength()

Description copied from interface: DataChunk

Get data chunk length

Specified by:

getLength in interface DataChunk<StringPoint,StringDataChunk>

Returns:

data chunk length

getEstimatedSize

public int getEstimatedSize()

Description copied from interface: DataChunk

Get estimated size in bytes.

Specified by:

getEstimatedSize in interface DataChunk<StringPoint,StringDataChunk>

Returns:

estimated size in bytes

getDataType

public TimeSeriesDataType getDataType()

Description copied from interface: DataChunk

Get data type.

Specified by:

getDataType in interface DataChunk<StringPoint,StringDataChunk>

Returns:

the data type

fillBuffer

public void fillBuffer(CompactStringBuffer buffer,
 int timeSeriesOffset)

Specified by:

fillBuffer in interface StringDataChunk

fillBuffer

public void fillBuffer(BigStringBuffer buffer,
 long timeSeriesOffset)

Specified by:

fillBuffer in interface StringDataChunk

tryToCompress

public StringDataChunk tryToCompress()

Description copied from interface: DataChunk

Try to compress the chunk.

Specified by:

tryToCompress in interface DataChunk<StringPoint,StringDataChunk>

Returns:

the compressed chunk or itself if compression is not efficient enough

splitAt

public DataChunk.Split<StringPoint,StringDataChunk> splitAt(int splitIndex)

Description copied from interface: DataChunk

Split the chunk in two parts.

Specified by:

splitAt in interface DataChunk<StringPoint,StringDataChunk>

Parameters:

splitIndex - the split index

Returns:

both chunks

append

public StringDataChunk append(StringDataChunk otherChunk)

Description copied from interface: DataChunk

Append the chunk with the one given in argument, and return the result. "This" dataChunk and the one in argument remain unchanged. The two chunks have to be successive, i.e : this.getOffset() + this.length() = otherChunk.getOffset()

Specified by:

append in interface DataChunk<StringPoint,StringDataChunk>

Parameters:

otherChunk - : the chunk to append with this object. It has to be the same implementation as this object.

Returns:

stream

public Stream<StringPoint> stream(TimeSeriesIndex index)

Description copied from interface: DataChunk

Get a point stream.

Specified by:

stream in interface DataChunk<StringPoint,StringDataChunk>

Parameters:

index - the time series index

Returns:

a point stream

iterator

public Iterator<StringPoint> iterator(TimeSeriesIndex index)

Description copied from interface: DataChunk

Get a point iterator.

Specified by:

iterator in interface DataChunk<StringPoint,StringDataChunk>

Parameters:

index - the time series index

Returns:

a point iterator

writeValuesJson

protected void writeValuesJson(com.fasterxml.jackson.core.JsonGenerator generator)
                        throws IOException

Specified by:

writeValuesJson in class AbstractUncompressedDataChunk

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
